Motion Boundary Histogram (MBH) features are generated with the aid of the
improved trajectories [1]} executablehttp://lear.inrialpes.fr/people/wang/improved_trajectories.
We train another battery of one-versus-rest SVMs using a linear kernel on the MBH features,
and use the resulting SVM scores \(S^m = \lbrace {s_{1}^{m},...,s_{c}^{m},...s_{C}^{m}}\rbrace \)  as global video features.
